The correct answer is option 2, Original jurisdiction.

Option 1, Advisory jurisdiction, refers to the power of a court to give advice or opinions on legal matters, but the Supreme Court`s power to decide disputes between the Centre and State goes beyond providing mere advice.

Option 3, Appellate jurisdiction, refers to the power of a court to hear and review decisions made by lower courts. However, in the case of disputes between the Centre and State, the Supreme Court has the initial authority to hear and decide on the matter, rather than reviewing a lower court`s decision.

Option 4, Constitutional jurisdiction, generally refers to a court`s authority to interpret and apply the constitution. While the Supreme Court does exercise constitutional jurisdiction, it specifically exercises original jurisdiction in cases involving disputes between the Centre and State.

Therefore, the power of the Supreme Court of India to decide disputes between the Centre and State falls under its Original jurisdiction.
